Signed Rolex, Retailed by Tiffany & Co., Oyster Perpetual Date, Submariner, 660ft=200m, Ref. 1680, Case No. 5'500'127, Circa 1978

Rolex's first Submariner with date, the reference 1680, was introduced in 1968 with much success. Collectors will make a distinction between a reference 1680 with red writing on the dial and a reference 1680 with all-white writing as the present watch. Rolex changed to the all-white print dial in 1976/77, marking the end of red writing on the Submariner. The present watch is made notable by the Tiffany & Co. retailer signature on the dial, which is a rare find on 1970s sports Rolex models.
